Divided and this application filed.Hatch 1929. Serial No. 348,389. g T I The present invention relatesgenerally to the forming of angle bars used in rail joint construction,and has to domore particularly with the reconstruction of worn anglebars. It has particular reference to a process or method of treating theworn bar so as to provide accurately finished fishing surfaces at boththe flange and the head of the bar,

and accurate spacing of such surfaces.

The type of bar referred to is that more commonly used'as fish platesfor rail joints. Each rail joint is commonly supplied with two suchplates or bars, each presenting wedge surfaces to head and flange of therail. Both plates are bolted together through the rail Web. Theconstruction is such that the rails and plates have registering holesfor the clamping bolts.

In spite of the use of such plates, the jointscan not be made as rigidas any portion of a single rail. No portion of the rail is peri'ectlyrigid and the heavy load, concentrated at single traveling points,causes the rail to flex. The ends of the rails are most subject toflexing and the sudden transfer or a load by the passage oia car wheelfrom one rail to another causes rapid and violent relative.

motion of abutting rail ends past each other. This motion causes thefish plate to oscillate to a slight extent, rubbing on the moving rails.The rubbing of the parts wears down the wedging surfaces.

These worn plates, however, contain substantially all the initial metaland retain their general initial form. The apparent defects arepractically superficial so that the worn plate provides a skeleton andalso a mass of metal for rebuilding it into a useful form.

The general object of the present invention is to provide a process ormethod or reconditioning and reforming worn plates.

Another important object of the invention is to provide a die movable inone direction by applied pressure so arranged that it exerts pressuresubstantially laterally Wltll respect to the applied pressure.

Oither ancillary objects and advantages of the invention will beapparent from the tollowing description as set forth in connection inwhich the trafilc travels in one direction l(:nly, showing the wear ofthe head of the ar;

It is to be understood that the invention is susceptible to variousmodifications and departures difiering from the steps and a paratusherein disclosed. Consequently, t e detailed description hereinafterfollowing and 50 vertical, when t e bar is in a formin die of a used ina one way track showing the characteristic wear of such a bar. The twohalves of the bar do not wear equally on a one-way track and one-halfwears more and different- 1 from the other. In Fig. 1 one half 10a of Lt e bar-head 10 is' worn at the center consider- -ingidie cavity. Thereis, therefore, no great 7 di 0 fit properly, which is to be expected calmovement.

ably less than the other half 106 which is deepest at the center of thebar and tapers sharply to midwa'y'between the center and the end of thebar. The same is true of the flange 12 which although only sli htly wornat half 12a is much worn at ha1 f 12b, particularly at the center of theban The extent of such wear is approximately as shown by the parallelshade lines in Figures 1 and 2. Bars with one way track wear as inFigures 1 and 2 are the most difiicult to reform, and it is impossibleto reform flange wear as in Figure 2, without some special methodwhereby great pressure can be exerted on the left one half of the bar tobring the worn one half to a proper finish without any break between thetwo halves or rtions of the fishin surface of the bar. have found thatin the prior art one way track bars have frequently een scrappedrathercthan attempt reforming, and that of those reformed, manyl do notw ere the worn alf of the flange fishing particularly has not beenaccurately restored. In the reforming of rail 'oint bars, the greatestaccurac must be .0 erved in the formin of the fis ing surfaces and theheight of the ar. The head of the bar presents a body. of metal ofconsiderable mass which can be readily spread by vertical pressure onlyapplied thereto in such manner as to force the fishing surface of thehead into tight contact with the corresponding wall of the formultyencountered in properly reforming the headof the bar. The flange of thebar, on the contrary, is relatively thin and is disposed at an a knotfar removed from the press in which the dies have relative verti- Theangle of the flange to the direction of relative movement of the dies issli ht, whether the relative movement of the ice be vertical orhorizontal. For this reason, the pressure applied to the flange by theforming die is indirect and it is impossible, in dies of the prior art,to obtain the proper amount of pressure on the flange, such pressurebeing properly directed to force the fishing. surface of the flange intoforming contact with thecorresponding area of the wall of the diecavity. The chief difliculty,

therefore, encountered in the refo rmin of rail joint bars is in theforming of the shing surface of the flange of the rail with absoluteaccuracy. This is highly important in this art. A further importantfeature of my invention is that the accurate forming of the fishingsurface of the flangn and toward the flange of the bar, the direction inwhich the applied ressure is converted having'components oblique to thedirection of the first or applied pressure.

This accomplishes important mults in that it subjects the flange of thebar to pressure in the direction of such flange, this pressure servingto force the flange tightly a ainst the corresponding forming surface 0the wall of the die cavity. The bar is thus spread slightly in thedirection of the g flange and the fishing surface of the flange isformed accurately by the corresponding surface of the formin die.

I am also enabled, by this .meth to apply suflicient pressure to theflange of a one way wear bar to assure proper reforming of the flangewith a continuous and accurately formed fishing surface.

Whlle my invention is directed mainly toward the proper reforming 'oftheflange fishing by lateral pressure, there are cases where it is desiredto direct this lateral pressure toward the head portion of the bar. Insuch cases, the resistance caused by artial formation of the flangefishing, orces the dies into alignment against the lock collars as shownin i 7. v

In order that the a plie l pressure for reforming the bar may beconverted into 'pressure in another direction, I provide dies which aremounted for relative lateral movement as well as relative movementtoward and away from each other. It will be understood that the dies andpress illustrated and described herein are shown merely by way of exam1e and my method or. recess may be practiced in anyothersuitab e manner.In Figures 5 and 6, I have illustrated a press and dies suitable forracticing my invention. The press and dies illustrated are similar tothose disclosed in my copending application for Means for reforming wornangle bars, filed July 16th, 1926, Se-' rial No. 122,864, which hasmatured into Patent Number 1,712,506, dated May 14, 192?, of which thepresent application is a CllVlSlOIl.

44 and 45, and. a vertically movablecross.

head 46.

Upon the base, there is a horizontally slidable wedge 47 fixedlypositioned between adjusting screws 48 and 48a. A wedge shaped bolsterplam 47a is employed to engage the wedge47 for vertical adjustmentthereby. Upon the bolster plate, a die holder 49 is fixedly mounted. Alower die 50 is locked in the die holder between a plate or block 51 anda longitudinal wedge 52. A variation ofthis construction, used in theordinary toggle-press, is a die holder bolted to the solid bed of themachine with the wedge adj ustment above.

The die above described is considered as fixed and another die 53 ismovable toward it, being carried by the cross-head 46. A

die holder 54 is bolted to the cross head, but

the upper die 53 is not fixedly mounted in said holder. The upper die 53is narrower than the lower die 50 and is positioned between twostripping bars 55 r1gidly secured to the die. The bars have endsextending beyond the uprights 44 and 45 of the machine as shown inFigure 6. The die 53 is held resiliently against the bottom of the dieholder by a spring suspension of the stripping bars 55. A suitable meansfor so suspending the die comprises a cross rod 56 between adjacent endsof bars 55 forming a rectangular frame. Ea'ch rod 56 is suspended by apair of hangers 57 vertically movable through a guide in the form of ashelf or bracket 58 carried by the cross head 46. Rollers 59 are mountedon the. rods 56 to bear against the die holder. Between the shelf andthe headed end of each hanger, there is a coiled spring 60 surroundingthe shaft of the hanger. I

The machine is also provided with knockout means to free the work piecefrom the dies: The lower die has a knockout pin 61 operated by a rod 62passing downwardly through the die holder and the base. The up per diehas a similar knockout in 63 operated by a rod 64 passing upwa ly intothe crosshead-to a transverse opening 65 there-- in. A bar 66, joined tothe rod 64,extends through opening 65 and has its ends projecting fromthe cross-head to strike parallel cross-bars 67 and 68 secured to theuprights. As the dies 55 travel up, the bar 66 contacts the cross bars67 and 68, and the knockout pin becomes stationary and acts to strip thework from the die during the further upward movement of the cross-head.

A four hole bar B is shown in the press between dies '50 and 53. Roundpins 69 and oval pins 70 are shown piercing the bar B.

The pins are associated with the upper die" and move downwardly with itentering holes 71 in the lower die. All the pins are round ointed to aidin forming the holes in the bar. The pins are mounted so as to bemovable relative to the upper die, and in the present construction arecarried directly by the cross-head. Any suitable or preferred means forattachingthe pins to the cross-head may be employed, it beingsuflicientthat'the pinsare suitably secured to the head.

Relative movement of the pins and the die 53 is produced by arrestingthe. upward motion of the die while permitting the pins to be carriedupwardly by the cross-head. This is readily obtained by providing a stopfor the resillently mounted .die.

The stop comprises bars 72 and 73 secured on opposite sides of theuprights 44 and 45 and disposed in the path of the ends of strippingbars 55 carrying the die 53. 'When' the 73, upward movement of die 53 isarrested and, during the continued upward movement of the cross-head,the pins are withdrawn from the bar. If the bar adheres to the die afterwithdrawal of the pins, it will be stripped from the die by knockout pin63 as the cross-head reaches the uppermost limit of its up stroke.

Spring latches 74, four in number, are arranged to hold the upper diedown while the cross-head and die holder move upwardly.

Each latch comprises a resilient projecting hook 75 of semi-circularshape to engage rod 56. These latches are mounted on the lower dieholder 49. The release of the latch is effected by the springs 60reachingtheir limit of compression so that a positive pull by thecross-head draws the rod 56 away from, the latch. When the rods 56 arereleased from the latches, the die is projected upwardly by expansion ofsprings 60 at a greater speed than the upward movement of the cross-headthus causing the pins to strike thebar and strip it from the die. Thevarious steps in the stripping operation need not be set forth in moreetail herein, it being noted that the stripping of the work from the dieis fully described in my copending application above referred to and isclaimed therein.

An important feature of the die pres above described, which is ofprimary importance in practicing my method of reforming bars, is theconversion of vertical die pressure to substantially lateral pressure.bar B is so positioned between the dies that the wedge surfaces convergedownwardly. The object of the die pressing is to reform the bar byspacing the wedge surfaces 11 and 13 further apart and at the properangle. The dies, of course, determine the limit. I This requires alateral spreading, while the die holder 54 exerts only verticalpressure. The most important feature of my invention is, that thislateral spreading is in large part diverted in one-direction, ascompared with The ordinary spi'eading in two opposing direc-- tions,this method of balancin lateral pressure to an unbalanced shape beingdirected to the proper reforming of the thin broad-surfaced andangularly positioned flange portion of the bar.

The above described mounting of the upper die holder permits lateralmovement of the up er die 53- substantially parallel to the bars 67 and68 and rods 56. This is highly desirable as contributing to theconversion of vertical pressure to substantially lateral pres sure.Another contributory factor is the form of the bar, and another factor,which is of great importance, is the design of the registering surfacesof the up er and lower dies. To permit this desired ateral motion of theupper die, the pins 70 and 69 may be mounted for lateral shiftingwiththe die, 02

the holes in the u per die through which the pins extend may e providedwith a suitable clearance c. The holes 71 in the lower die are alsolarger than the pins to permit relative movement between the dies.

In Figure 7, I have illustrated one form of my invention particularlysuitable for reforming the head portion of the bar and also adapted forreforming the flange portion, as there are occasional cases in I-beambars where it may be used, first reforming the flange fishing and then aprojecting portion of the head. Two dies 76 and 77 are mounted forrelative vertical movement, 76 being movable and 77 being fixed. Thedies are as sumed to be fully closed under full pressure.

- In this case, it is necessary to move the line wy to the left apredetermined amount, into the dotted 'line position indicated, inaddition to re erly reforming the flange fishing '--81 his is done bydraughting the flange at VW '1! amount so that its increasing resistancenear closure will force die 76 to the left pushing :vy to its dottedline location and no more, the lock 8283 restricting movement to theleft and there being no more movement to the right because the lock82-83 is arallel to the vertical motion of the u per 'e. However, myinvention is directe' mainly to properly reforming the flange portion ofthe bar. Usually the head is a body of such mass that the problem ofreforming it is simple compared to that of reforming the relatively longand thin flange of the bar. The flange not being far removed from thevertical is subjected to but indirect pressure. If this angle of theflange with the vertical were eater, the pressure exerted thereon'wouldI; less indirect, but such pressure is limited because of the head angle78-79 of not over 14 degrees with the vertical, and there are otherobjections to placing the back of web 14 much removed emthe horizontal.descends, the flange portion 80-81 thereof encounters the correspondingportion of the As the movable die 7 6 bar which-exerts pressure on thedie toward the left where a vertical wall 8283 of the die 76 encountersa corresponding side or wall of the lower die 77. These walls constitutethe die alinement or lock and, as illustrated, these walls are vertical,that is, are arazllel to the direction of movement of the ie 6.

An considerable lateral pressure againstcollars 82-83. For ordinaryflange reforming, the method is therefore ineffectual.

InFigure 8 I have illustrated one form of die structure whereby myjm'ethod'of accurately reforming dies I can be practiced. Dowel pins 84-are adjustably secured by set screws 85 in recesses in a lower fixed die86. These pins project upwardly above the die for engagement intobushings 87 secured by set screws 88 in suitable recesses in an uppermovable die 89. This upper die is mounted for lateral movement, as inFigures 5 and 6.

The pins 84 are tapered and the parts of the die structure are sodisposed and related that the upper die 89 in its descent first contactsflange 12 of bar B along surface 80-81 of the die 89 so as to shift ittoward the left out of alinement with die 86. As downward movement ofdie 89 continues the dowel pins 84 enter the bushings 87 and coacttherewith to shift die 89 toward the right into alinement with die 86.In this manner the vertically applied pressure of die 89 is converted tolateral pressure toward the right, that is, in the direction of theflange of the bar thus forcing the flange against the cooperating wallof the die cavity under forming pressure.

In this. manner, I assure that the fishing surface of the flange isaccurately formed, .1

which is of primary importance. As previously noted, the head of the barconstitutes a body or mass of metal of suflicient extent to be readily sread into forming contact with the fishing orming surface of the dieproducing an accurate fishin surface on the head. It is not essential tat the die 89 be offset to the left durin the first part of its closingmovement, in cases, since very satisfactory results are accomplished byhaving the die 89'initiall offset to the left relative to die 86 andalinmg die 89 with die 86 as it moves into full closed position. Theoperation in converting the vertical applied pressure to lateralpressure in the direction of the flange of the bar is the same in eithercase. This form of die structure is not, from a practical standpoint,the best and may be considered rather crude. However, it illustrates onemeans by which my method may be practiced. The pins 84 and the bushings87 wear away rapidly due to the great amount of pressure to which thecontact surfaces of these members are subjected. After the surfaces haveworn to such an extent as to render the operation of the diesinaccurate, which occurs quite rapidly, the set screws 85 and- 88 areloosened and the pins and the bushings are given a quarter turn to'present new wearing surfaces. After the pins and the bushings have beenadjusted four times and these wearing surfaces have been used to such anextent as to render the dies inaccurate, the pins and bushings are ofnov further use and must be replaced.

A less practical method, although following the teaching of myinvention, is to use tapered ways for the cross-head of the press sothat the cross-head will shift slightly sideways near the bottom of itsstroke. A. similar eifect may be gained by using untapered cross-headways placed laterally off of their natural positions so as to opposelateral shifting of the dies as they meet the resistance of the barflange. I find in practice, however,

that the most satisfactory results are accomplished by confining meansfor insuring lateral foriningpressure to the die holders or dies,preferably the latter, in that the side lock or lateral thrust means maybe machined to take up wear at the same time as the dies, and because itis diflicult to make and preserve accurate alignment when employingmeans'in the press, die-holders, or anywhere not in the die themselves.

In Figures 9 and 10, I have illustrated dies which I find to be highlyeflicient in practicing my method of reforming bars. Re-

ferring more particularly to Figure 9, an upper die 90 is mounted in apress for movement vertically toward and away from a lower fixed die 91,the die 90 being also mounted forlateral movement in the'same manner asthe upper die illustrated in Figures 5 and 6. The two dies are providedwith a diagonal thrust lock 92-93 fitted accurately throughout thelength of both dies so that when the dies are closed and are tight toether at 92-93, the draft or reduction of t e flange area 80-81,80'-81-is assured. The action is as follows-as the upper or moving diedescends and nears the completion of. its stroke, the die surfacebetween the points 80-81 encounters the corresponding portion of theflange 12a of the bar B, striking a glancing blow which shifts the topdie to the left until the lock surfaces engage at 92-93 which surfaces,being a diagonal, force the top die to the right and continue to do sountil the completion of the stroke. This gives the desired effect 11onthe flange-a powerful and increasing ateral pressure at 80-81 to forcethe metal of the flange hard against the lower die at 80-81' an securethe desired work upon the flange bearing portion of the bar. It is aneffective means for securing powerful lateral pressure from verticalpressure as disclosed in my copending application above identified.

A further practical advantage of this die structure is thatwearresulting from friction is'quickly compensated for by dressing downthelock-surfaces and bar recesses jointly, the wear of the lock surfaces92-93 being restored when the wear on'the die fishing surfaces 9-95 vand80'-81 require restoration, both being brought back accurately to properfit and alinement in both dies by machining down or sinkingthepassineach die vertically. The surfaces 92-93 and 80-81 in,the top dieand 94-95 and 80-81' in the bottom die, being opposing diagonals, arerestored to their proper horizontal alinement by slight verticalmachining. This provision for readily correcting wear is'of greatimportance, second only to the provision for transforming vertical intolateral pressure; and both solve the difficult problem of properlyreforming the flange fishin which would otherwise be extremely difiicut, if not impossible, since in the prior art most of the pressure isdeflected away from the bar flange to the head and the web portion ofthe bar and accurate forming of the fishing surface of the flange isimpossible.

In practice I use several variations of the diagonal thrust idea aboveset forth. In short thick flanged bars, such as illustrated in Figure 9,the diagonal thrust is at a greater angle to the vertical than in diesused for reforming long thin flanged bars, such as illustrated in Figure10, the lesser angle resulting in less lateral thrust.

The method above described of securingproper flange forming pressure,which is essential for properly reforming the flange fishing surfaces,even in cases of bars which are not excessively worn, frequently callsfor assistance in the case of one way track bars previously described,and of badly corroded or worn bars, for it is much more difficult tosmooth out irregularities and uneveness than it is to reform a flangesimply worn down from end to end. I, therefore, provide furtherassistance in these extreme cases by the use of means whereby the webportion of the bar is thinned laterally by increased draft at 80-81 inthe central one-third of the bar making the flange thinner at its centerver tically when in its upright position bolted to the rail. This isshown in Figure 9 and forms the subject matter of my copendingapplication for renewing worn angle bars, filed October 22, 1929. Thisconcentration of pressure at the center, combined with the lateralthrust by the diagonal lock, gives the desired result so thatirregularities such as one way track flanges, pitted and groundv flangesand flange lips are pressed out. As

regards the bar head, lumps from welding in metal, ground recessesforincipient cracks and deep pittings partially ground out, are smoothedout by the assistance, when needed, of laterally beveling the dies soaswto thin the bar at the center as disclosed in my copending aplication, Serial No. 260,695, above .identi ed.

In securing lateral pressure, I do not wish to be limited to thediagonal thrust collar,

with the direction of pressure gives no lateral thrust toward the flane. but gives lateral thrust toward the hea by a predeters mined amount.Any departure from the vertical gives side thrust toward the flange l asincreasing with the angle, althou h more power is lost in friction atthe loc as'the angle increases. In Figure 10, the construction andoperation of the dies is essentially the same as that of Figure 9 exceptas to the angle of-the lock and the greater draft exerted on the bar.The side thrust in Figure 10 is less than .the side thrust in Figure 9,the bar B" of Figure 10 bein of a different type than that of Figure 9,w ichlatter bar requires greater pressure and side thrust in thedirection of the flange to properly reform it. In its broader aspects,my invention consists in reforming the bar by subjecting the same toforming pressure in a forming die and converting t e initially appliedpressure to pressure in a direction having a component substantially atright angles to the direction of the applied pressure, that is, thedirection of the converted pressure being substantially oblique to thedirection of the applied pressure and toward the flange of the bar,although in certain instances illustrated by Fig. 7, lateral motion andpressure is desired not toward but away from the flange.

In practice I prefer to set the bar as in Figures 7 to 10, so that theback ot the web is perpendicular to the direction of the'initiallyapplied ,ressure, this facilitating the useof pins in t e upper die topreserve the size and acin of the bolt holes. However,

in cases w ere t e pins are not used, the bar may be set at any angle,such as that of Figure 11, either die being movable in the directionindicated by the arrows. In this figure 96 designates the upper die and97 the lower die. These dies may be placed in a vertical press, a sidebulldozer, or other suitable machine for oieerating the dies. It will benoted that in igure 11 the bar is tipped at an'angle to the horizontal.In Figure 13, the bar is placed in the die reversely to Figure 11 and isalso tipped from the horizontal. In this figure 98 designates the upperdie and 97 the lower die. This tipping of the bar renders it possible toget more direct pressure on the flange of the bar than is possible whenthe die is not tip (1, but the amount or extent to which the g whichmust have slight clearance so that t e bar will not be stuck fast in thedie after it has been reformed, i

In Figure 11 the thrust lock is on the die -and is designated 100; Thislock is at the.

, r can be tipped is .governed by the head fishin being designated 102and the lower die 103 in this figure. I v

In Figure 14 the upper die is designated 104 and the lower die 105 thelock 106 being at the flange side of the bar. In this figure the bar istilted and is disposed with the flange down, the arran ement of the barillustrated being the best or securing a fair balance of pressure. Thisarrangement of the bar 1s, however, open to two serious objections; onebeing that the radius A would be I over-filled necessitating machiningto the proper curve, and the'other being that the two fishmgs, head andflange, being in se arate dies would result influctuation of fis ingheight. In Figure 15 the up or die is designated by 107 and the lowerd1e by 108, the ock 109 being at the head side of the bar. Thearrangement of the bar illustrated in this figure is objectionable inmost cases although in some instances it may be found advanta eous. Ofthe various positions which e bar may Figures 11 to 15, inclusive, thepositions of the bars illustrated in Figures 11 to 13 are the mostpractical in relation to pressure direction, in the order named, and inall cases the lack of pressure balance makes advisable some means forlateral thrust to properly reform the flan e. Under ordina condi--tions, however, prefer to position t e baras illustrated in Figures 8to 10 so that the ressure is a of and t is initially ap lied pressure isconplied to the bar from one side t erebeset at illustrated in vertedtopressure app ed to the flange of the bar in the direction thereof foraccuratebar in one direction and then a pl i 1 a supplementary pressurein anotliern 1y forming the fishing surface of the flange 1,eos,see
